With live streams of concerts like Coachella and Lollapalooza, and performances from bands like U2, YouTube is no stranger to hosting the planet’s big rock fests. So we’re adding another to the list: Rock in Rio 2011.

From September 23 to October 2, some of the biggest bands in the world will be live on YouTube performing at the world’s next mega-concert, Rock in Rio 2011 from Rio de Janeiro, Brazil. The Rock in Rio YouTube channel already has an early look at some of the bands in the lineup, including Metallica, Red Hot Chili Peppers, Katy Perry, Elton John, Rihanna and more.

We’ll be live around the world in 24 different languages, so if you can’t attend in Brazil, clear your schedule and get ready to rock!
